Servo system

摘要

An apparatus for directing a selected fluid to a movable substrate includes a nozzle connected to a movable support, and a supplying mechanism for providing the fluid to the nozzle at a pressure which provides for a selected fluid flow rate from the nozzle. The supplying mechanism includes a torque conduit section which has a longitudinal torque axis thereof and is configured to absorb torsional energy produced by moving the support. An actuating servo rotates the support to move the cutter nozzle along a selected cutting path, and the actuating servo has a servo axis of rotation which is arranged substantially collinear with the longitudinal axis of the torque tube conduit section.
